(i) Value of vibration of a particle is described as the number of vibrations done by particle in one second.
(ii) It is the value of total wavelengths traversed by the wave in one second.
(iii) Value of frequency are hertz (Hz) and per second.
who is first law of motion?
To determine the acceleration due to gravity using a simple pendulum. Apparatus: Pendulum, meter scale, stand, stop watch, vernier callipers. Procedure: 1. The diameter of the bob

Example of like and unlike parallel forces
A bob hanged to astrirg in a box .it is displaced to an agle of 45 .then fid the acceleration of the box at this moment. Ans) gsin45,that is 10/1.4142.as it would have only tangen
A cab driver in a hurry is sitting at a red light. When the light turns green she rapidly accelerates for 3.50 s at 6.80 m/s 2 . The next light is still red. She then slams on
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
A streamlined body given relative density ρ1 falls into air from a height h1 on surface of a liquid of relative density ρ2 where ρ2 > ρ1. find out the time of immersion of body int
